DISCRIMINATION ON THE GROUND OF A DISABILITY
35 Psychological disabilities may constitute a "disability" within the meaning of the Act. Such psychological disabilities may cause a person to behave differently from the way in which a person who does not have that disability would behave. However, where an educational authority is unaware of the disability, but treats a person differently, namely, less favourably, because of that behaviour, it could not be said that the educational authority has treated the person less favourably because of the disability - see Tate v Rafin [2000] FCA 1582 paragraphs [64]-[67].
36 Thus, there is a distinction to be drawn between a disability within the meaning of the Act, on the one hand, and behaviour that might result from or be caused by that disability on the other hand. Less favourable treatment on the ground of the behaviour is not necessarily less favourable treatment by reason of the disability. The position might be different in a case where the disability necessarily resulted in the relevant behaviour. That is not the present case. The behaviour of the Complainant is not ipso facto a manifestation of a disability within the meaning of the Act nor of any disability of the Complainant within the meaning of the Act.
37 As I have observed at paragraph [22] above, the Commission appears to have treated the Complainant's disability as falling within in paragraphs (f) and (g) of the definition of "disability" in s 4. The term "disability" is defined in paragraphs (f) and (g) in terms of a"disorder or malfunction" and a"disorder, illness or disease" respectively. Each of those expressions is then limited by a relative clause that describes certain symptoms of the "disorder or malfunction" or the "disorder, illness or disease". It is only a disorder or malfunction or disorder, illness or disease that is manifested in certain symptoms that will constitute a disability. Thus, it is clear that it is the disorder or malfunction or the disorder, illness or disease that is the disability. It is not the symptom of that condition that is the disability.
38 It would have been possible for the Parliament to define disability by reference to symptoms that have a particular cause. For example, it would have been possible to define disability as "disturbed behaviour that results from a disorder, illness or disease". If that were the approach adopted, particular behaviour would be a disability. However, the drafting approach also leads to the conclusion that behaviour is not a disability.
39 Some light is thrown on the way in which s 5 operates by the language of s 6. Section 6 of the Act is concerned with indirect discrimination. The discrimination described in s 5s 6 is often referred to as "indirect" discrimination. The major difference between the two types of discrimination is that, in the case of direct discrimination, the treatment is, on its face, less favourable. However, in the case of indirect discrimination, the treatment is on its face neutral but the impact of the treatment on one person when compared with another is less favourable - Walters v Public Transport Corporation (1991) 173 CLR 349 at 392.
40 The presence of s 6 in the Act indicates that a construction must be given to the expression "on the ground of" in s 5 which is literal. That is to say, if an educational authority treats a person less favourably than it would treat another person in the same or similar circumstances on the ground of the first person'semphasis must be placed on the expression "because of the aggrieved person's disability" in s 5. In particular, "disability" must be interpreted literally, in accordance with the definition in s 4. As I have indicated in paragraph [37] above, the definition draws a distinction behaviour, that is not the same as treating that person in that way on the ground of a disability, in circumstances where that behaviour might or might not be caused by or be the result of that disability. Thus, discrimination on the ground of a particular behaviour will not necessarily be discrimination on the ground of a disability, even if that behaviour is caused by or is the result of a disability within the meaning of the term as defined in the Act. between disorder or malfunction or disorder, illness or disease ("the disability"), and particular symptoms of the disability. Section 5 clearly contemplates a situation where a complainant is discriminated "because of" the disability. Section 6(a), on the other hand, contemplates a situation where discrimination operates indirectly. One example of such indirect discrimination would be requiring a complainant to act in a way that was made impossible by a person's disability. Thus, an illustration of conduct that might fall within s 6(a), based on the facts in the present case, would be the situation where the School expelled the Complainant because he continued to swear and demonstrate violent behaviour.
41 The Commission concluded that the Complainant's behaviour occurs as a result of his disability and that, accordingly, his behaviour is so closely connected to his disability that, if less favourable treatment has occurred on the ground of the Complainant's behaviour, then that will amount to discrimination on the ground of his disability. The thrust of the State's complaint under this head is that the Commission erred in equating the manifestation of a disability with the disability itself. The State contended that, in concluding that discrimination on the ground of behaviour constituted discrimination on the ground of disability that had caused that behaviour, the Commission was in error.
42 Counsel for the complainant contended that there was no error of law on the part of the Commission in making its determination. Counsel pointed to the finding that:
"The reason for [the complainant's] exclusion… related to [his] behaviour leading to the five suspensions and throughout the period of his enrolment at [the School]. It also related to [the Principal's] judgment that [the Complainant] could not operate in a regular high school environment as a result of his disability. [The Principal's] underlying reasoning… included issues broader than just behaviour. Certainly [the Complainant's] behaviour (and its impact on himself and other students and staff) was a factor, but it was not the only factor. The decision also related to [the Principal's] perceptions of [the Complainant's] success socially and educationally."
43 However, it is clear from the following finding that the Commission's reasons were based on a conclusion that the Principal's decision was made by reason of the Complainant's behaviour rather than his disability:
"[The Principal's] decision was taken as a result of [the Complainant's] behaviour, which [the Principal] believed impacted on the safety and welfare of [the Complainant], other students and staff. It was also taken, in [the Principal's] view, as a result of [the Complainant's] inability to cope with the stresses of high school life, as a result of his disability. Whilst I am sure [the Principal] took this decision for what he saw as [the Complainant's] best interests, none the less it was in breach of sections 5 and 22(2) of the Act." [emphasis added]
44 Thus, the Commission found that the Principal made his decision because of the Complainant's behaviour and not because of"because of" his disability, albeit that the behaviour was caused by the disability. The Commission's conclusion was visciatedvitiated by its acceptance of the proposition that, because the Complainant's behaviour was so closely connected to his disability, less favourable treatment on the ground of behaviour would amount to less favourable treatment on the ground of disability that caused that behaviour.
45 The Commission, in effect, treated the behaviour of the Complainant as necessarily being a manifestation of his disability. However, while, in the case of the Complainant, his behaviour was in fact the result of or caused by his disability, that behaviour is not necessarily caused by or the result of a disability such as the disability of the Complainant. As such, the Commission misconstrued the operation of ss 5 and 22(2) of the Act. It follows that the Commission erred in its approach as a matter of law, such as to attract s 5(1)(f) of the ADJRAct.
